Preheat oven to 375 degrees F (190 C) and line a standard 9×5-inch loaf pan with parchment paper.
In a large mixing bowl, prepare flax eggs by mixing flaxseed meal and water and let rest for 5 minutes. Then add applesauce, maple syrup, coconut sugar, baking soda, baking powder, sea salt, and cocoa powder, and whisk again.
Next add the melted coconut oil and almond milk and whisk to combine. Add grated zucchini (that's been squeezed of excess moisture) and stir to combine.
Add gluten-free flour, oat flour, and almond flour and whisk until just combined. If the batter appears too thick, add a touch more almond milk. But it should be thick and scoopable.
Lastly, stir in chocolate chips. Then transfer batter to the loaf pan and top with a few more chocolate chips (optional).
Bake 45 minutes - 1 hour or until a toothpick comes out clean and the edges feel semi-firm to the touch.
Let cool for 5 minutes in the pan. Then carefully lift onto a cooling rack using the parchment paper. Texture is best when cooled completely. Will keep covered at room temperature for 3-4 days or in the freezer up to 1 month.
